Need help implementing a function

Implement a function named "addTwo" that returns the sum of two floats. The function will accept two float numbers as arguments. It should add the two arguments together, and return the result. (No need to write the main function. Just write out the implementation for the addTwo function.)

thats the problem, i believe i'm missing something but when i test it on Xcode, it works. Let me know, thanks!

  • stephin
#import <stdio.h>

float addTwo(float a  , float b);
int main()
    float foo = 24.7;
    float bar = 35.3;
    printf("addTwo %f\n", addTwo(foo, bar));
    return 0;

float addTwo(float a, float b) {

    return a+b;

The code challenge is just looking for the implemetation of the function:

float addTwo(float a, float b) {
  return a + b;

That should clear the test.
